scnxws 7-7 through its cars Mounted on tho inceting rail 1 of the lower snsli tho lowor plate frzn'nc 9, which is proridcd witli i top plate 10 on which is 1nountcd tlic lock plotc 11. This lock plate is for-mod with o tapering circular rib l2, soc Fig. 3, irliic'c cxtcnds out from one side ior1nnnipulotinglmndic 13, said rib coming siiliotan iiiliy to a point at 14, whereby it adopted to better enter tlic catch as it swings around into the same. This pliitcis mounted on tho pivot pin 15, which pin is sqiiorcd as at 16 tlinougli the plate and ex.- tends down tl'irougli the top pinto 10 of the iromn. Ono end 17 of a coil spring extends through this pin and after taking several turns around the sonic thoopp'ositc cnd of sold spring enters tlic top plate oi tlic frarnc at 18 tlicroliy providing means for out0n1otici-illy and quickly opcroting the loci; plate to engage 't-.i1.(5'( &l1(ill as soon permitted to do so by the withdrawing of its retaining latch. This retaining lntch 19 is pivotiilly mounted noiir one end of the short shaft 20, the opposite end of said latch being turned upward to extend through the hole 22 in the top of the ironic and into the lock plate. The pivotod mid of said latch is provided with an overhanging finger 23, by which the soon is ongogcd and manipulated. This latch is normally hold in its up or locked position by the tension of the coil spring 24 which is wound around said slizil't 20,-onc end being arranged to. engage the underside of said latch to press it upward. Tlic trip lever 25 is also loosely mounted on this shaft 20 and provided with a horizontally extending pin 26 which is iidziptcd to project lioncotli tliv overhanging linger 23, said lcvcr is also providcd Wllili'flll ilp-tiirncd nd 2? which is adapted to in 011- gogcd by the slanting cdgc oi the noscon tho catch, in the monnvr illustrated in Fig. 2, to tip back said trip lcvcr, causing its pin 26 to cngzigo the finger 23 on the latch to withdraw the np-turncd and of tho latter from tho look plotc, wlicrcliy the operating spring;- of thc lock pinto will cause mid plot". to rotatc, and as soon as the window is closed into position this lock plate will follow around bencoth the catch on the oppositc mil cccuroly locking llic two sashes togctlicr.

A sash lock comprising a frame, a

pass the upper rail of the lower sash when the ed in said frame, a spring pressed latch for I vided a hook member 29 which is pivoted at 30 in the lock plate frame. This hook member is provided with a downwardly turned end 31 which is ada ted to engage a slot 32 formed to receive it in the looking plate. This hook is also rovided with a handle 33 by which it may be manipulated.

My improved lock is simple in construction, positive in its action and may be automatically o erated to positively lock the window each time the window is closed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:.

1. A sash lock comprising a frame, a spring-actuated lock plate rotatably n1ounted in said frame, a latch for retaining said plate, a catch on the op osite window sash, and a trip lever adapted to be actuated by said catch whereby said latch is operated to release said lock plate to move into engagement with said catch when the windows are closed.

2. A sash lock comprising a frame, a spring-actuated lock plate rotatably mounted in said frame, a pivotally hung latch for retaining said plate, a catch on the opposite window sash, and a pivoted trip lever for controlling said latch, said trip adapted to be actuated'bysaid catch whereby said latch is operated to release said lock plate to move into engagement with said catch when the windows are closed.

3. A sash lock comprising a frame, a spring actuated lock plate rotatably mounted in said frame, a spring pressed latch for retaining said plate and a trip lever for controlling said latch, a shaft in said frame oilv which both said latch and lever are loosely mounted, and means on the opposite window sash for receiving the lock plate and also for engaging and operating said trip to release said lock plate to move into engagement with said receiving means.

- top rail of one window sash is required to pass retaining said plate, a trip lever for cont-rollin said latch, a shaft in said frame on which both said latch and lever are loosely mountlease the lock plate to move into engagementwith said catch.

5. A sash lock comprising a frame, a

spring actuated lock plate rotatably 1nounted in said. frame, a spring pressed latch for retaining said plate, a trip lever provided with a laterally extending pin for engaging said latch,.a shaft in said frame on which both said latch and lever are loosely mounted, a catch on the opposite Window sash, the end of said trip lever being turned up to be engaged and operatedbysdid catch to release the lock'plate tonnove into engagement with saidcatch. 1

i 6. A sash lock comprising a frame, a spring actuated look plate rotatably mounted in said frame, a latch for retaining said plate, a catch on the opposite window sash, a trip lever adapted to be actuated by said catch whereb lease said loci plate to move into engagement with said catch when the windows are closed, and a manually operated'hook adapted to be moved into engagement with the lock plate to prevent'the same from being automatically operated when the window is brought to its closed position.

7. A sash lock comprising a frame, a spring actuated look plate rotatably mounted in said frame, a spring pressed latehfor retaining said plate, a trip lever for controlling said latch, a shaft in said frame onwhich both said .latch and lever are loosely mountsaid latch is operated to re-.
